Application filed April 2, 1920. Serial No. 370,848.

To all 'LUILO'HL it may com/cm Be it known that I, CARL ALFRED JOHN- sox, a citizen of the United States, and resident of New Redford, in the county of :iristol and State of Massachusetts, have in vented certain new and useful Improvements in Lamp-Brackets, of which the following is a specification.

This invention relates to adjustable lamp brackets, and has for its object to provide a simple, practical and effective device whereby an electric lamp suspended from a flexible line or cord, may be adjusted with its shade to hangat different angles to the axis of the line of suspension, whereby the light may be thrown at an angle instead of straight down when desired.

The nature and advantages of the invention will be better understood when the following detail description is taken in connection with the accompanying drawings, the invention residing in the combination and arrangement of parts as claimed.

In the drawings forming part of this specification, like numerals of reference indicate similar parts in the several views and wherein:-

Figure 1 is a side elevation illustrating the lamp and shade as being supported at an angle of substantially 90 to the axis of the line of suspension by my improved bracket.

Fig. 2 illustrates the supporting bracket arm as adjusted to hang the lamp at substantially 45 from the axis of the line of suspension.

Fig. 3 is a side elevation illustrating the lamp as hanging vertically or substantially parallel with the axis of the line of suspension.

Fig. 4 is a perspective view of my jointed bracket arm, showing the same as locked with the members at an angle to each other.

Fig. 5 shows the lower or clip member of the arm, which is designed to embrace the socket shell of the lamp.

Fig. 6 is the upper member of the arm, which is designed to engage the flexible suspension line or electric wire cord.

Fig. 7 is a perspective view illustrating the multiple hook member by which the two arm members are retained in adjusted position.

Ordinarily an electric lamp and shade when suspended from a line or wire hang in a vertical position, as illustrated in Fig.

of the drawings but it is found in practice of advantage to be able to adjust the hanging of this lamp so that its shade will throw the light at some particular angle relatlve to the axis of the suspension line.

The following is a detail description of one form of device which is adapted to accomplish this purpose lVith reference to the accompanying drawings, 1O designates an ordinary shade which may be secured by any suitable means to the usualelectric lamp 11, the neck portion 12 of which lamp is shown as extending through the top of the shade. My invention constitutes a bracket arm which is jointed at 13 mtermediate its opposite ends. The free end 14 of the upper member 15 of this arm 1s provided with lips 16 folded inwardly from the opposite sides thereof providing a socket having an opening 17 through which the flexible line or electric wire 18 may be passed. This upper arm is also provided with a, laterallyrextending, integral finger 19 which is cut from the edge of the stock andj'folded to lie at substantially a right angle to the plane of this arm.

The free end of the lower member of this ointed arm is provided with two resilient fingers 21 which serve as a clamp or clip to be snapped over the socket shell 12 of the lamp, whereby this member is readily secured in position to the lamp member. The outer end of this lower arm member is provided with an ear 22 to which the upper member is pivoted at 13. This member is also provided with laterally-extending hook portion 24 which is adapted to engage or hook around the flexible wire line to assist in preventing the lower arm from being disengaged from the lamp portion. This lower member is also provided with an car 23 to which a hook-member 25 is pivoted at 26. T his hook is provided with a plurality of notches 27 any one of which may be" caused to engage the laterally-extending member 19 of the upper arm 15, whereby the two arms may be locked at the desired angle relative to each other.

In applying my improved adjustable bracket to a lamp which is suspended by a flexible cord or line, it is only necessary to weave the cord into the socket 17 at the upper end of the arm member 15 and then to snap the clip fingers 21 of the lower arm over the socket shell of the lamp. It is now only ece sa y to Swing h m members 1 and 20 at the desired angle to each other and cause the desired notch in the multiple hook to engage the laterally-extending member 19 on the other arm, whereby the lamp is suspended at the desired anglexrelative to the axis of the line o'l -support and when it is desired to returnithe lamp to a vertical position it is only necessary to release the hook from engagement with its projection 19 and the'lainp immediately assumes its norm-a1 ver- ;tical position.

I have shown and described a line for retaining the two members of the bracket arm in adjusted position, but I do not wish to be restricted to any particular means for accom'plishing this purpose. 7

The device is extremely simple and practical in construction and effective in its operation. j

The foregoing description is directed solely toward the construction illustrated, but I desire it to be understood that l-reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim: 7

1. An adjustable lamp bracket comprising a supporting arm adapted to engage the flexible suspending conducting cord by one end and the lamp portion by the otherend,

said arm being jointed intermediate its ends,

and a connector between said armsfor retaining the members of said arm in adjusted position at different angles to each other.

2. An adjustable lamp bracket comprising a supporting arm jointed intermediate its ends, one eno of said arm being provided with a socket portion for engaging the flexible suspension conducting cord, the other end of said arm being provided with means for engaging a portion of the lamp, and a latch on one arm member adapted to engage the other arm member to hold said members at different angles to each other in adjusted position.

3. An adjustable lamp bracket comprising a supporting arm jointed intermediate its ends, one end of said arm'being provided with a socket portion for engaging the fieXible suspension conducting cord, the other end of said aim being provided with means for engaging a portion of the lamp, a lateral projection on one of said arm members, and a hook on the other of said arm members provided with a plurality of notches for engaging said lateral projection whereby one arm member may be adjusted at different angles relative to the other member and retained in adjustedposition. r

In testimony whereof I affix my signature in presence of two witnesses.
